[PATCH] DOC: Fix typos in README and CONTRIBUTING

[Joseph Herlant]

Hi,

Please find attached a patch to fix a few typos detected by misspell
in the README and CONTRIBUTING.
Even if one of them is on a listing of commits. I'm assuming that if
we want to enforce less typos in the commits, having one in the
contributing guide is not the best example.

Thanks
Joseph
